Application of GA3 also had significant effect on … Effect of foliar spray of plant growth regulators viz., gibberellic acid (GA3) and 1-Naphthaleneacetic acid (NAA) on yield and quality parameters on three China aster cultivars viz., Kamini, Poornima and Violet Cushion was investigated. NAA is a synthetic plant hormone in the auxin family and is an ingredient in many commercial plant rooting horticultural products; it is a rooting agent and used for the vegetative propagation of plants from stem and leaf cuttings. Hormones are produced naturally by plants, while plant growth regulators are applied to plants by humans. (2004) [22] for optimum embryogenesis. Corpus ID: 99058208. Minimum plant height was recorded on T 9 (control treatment). The effect of exogenously applied natural [indole-3-acetic acid (IAA), phenylacetic acid (PAA), indole-3-butyric acid (IBA)] and synthetic [1-naphthaleneacetic acid (NAA)] auxins on the growth and metabolism of green microalga Chlorella vulgaris was examined. The following concentrations of auxin (NAA) and cytokinin (BAP) were prepared and applied as foliar application to observe their effect on growth and yield in Spinach. EFFECT OF SADH, NAA AND GA3 ON GROWTH, YIELD AND QUALITY OF SAPOTA [Manilkara achras (Mill.) had highest significant increase in grain yield followed by T2 (GA3 45 g), T1 (GA3 30 g), T5 (NAA 200 g), T3 (NAA 100 g), T27 (Urea 2 g + C.C.) Additionally, several other naturraly occurring indole derivatives are reported to express auxin activity, including indole-3- ethanol, indole-3-acetaldehyde, and indole-3-acetonitrile. The increased fruit drop and decreased percentage of fruit set, delay in flowering are the major issues lead to low productivity in paprika. Petkova S, Popova N, Angelova Y, Stefanov B, Iliev L, Popov M. Inhibitory effect of some plant growth regulators and chlorosulfuron on growth, protein composition and proteolytic activity of maize seedlings. significant effect of growth regulators on growth parameters at T 2 (GA 3 @ 50 ppm at 40 DAS) where maximum plant height (107.97cm) was recorded, followed by T 5 (NAA @ 50 ppm at 40 DAS) plant height (104.31cm). Overall this study has shown that the plant growth regulators at different concentrations (60 ppm GA3, 12 ppm NAA and 15 ppm CPPU) applied using the swabbing technique greatly improved fruit growth and quality, when applied a week (2014) examined the effect of GA This is consistent with the effect of NAA on leaf colour variants of … Tas-e-Ganeshand Kismis chorny ADVERTISEMENTS: In this article we will discuss about Indole-3-Acetic Acid (IAA) and Auxin in Plants. In some algal species, auxin stimu- In majority of fruit plants fruit drop is controlled by spraying of NAA in different fruit crops in different concentration. & Biotechnol. The effect of plant growth regulator (NAA) on the yield potential of coarse rice was evaluated during rice growing season of 2004 and 2005 at the Postgraduate Agriculture Research Farm, Gomal University, Dera Ismail Khan, Pakistan. mg) (Davies and Hobes, 1981). Keitt was studied by Osama et al., (2015). Exogenous auxins acted in a concentration-dependent manner on algal growth. The higher concentrations of NAA inhibit growth and exert toxic effects on the plants so, optimum concentrations are required for find out to beneficial effects of NAA. KALIPATTI @inproceedings{Garhwal2015EFFECTOS, title={EFFECT OF SADH, NAA AND GA3 ON GROWTH, YIELD AND … Environmental factors that affect plant growth include light, temperature, water, humidity, and nutrition. Licensed Under Creative Commons Attribution CC BY Increase in plant height with the application of NAA was also reported by Lakshmamma and Subba Rao (1996) in wheat which is consistent with the results of our present study. Use and regulation. Result showed that 50 ... Effect of plant growth regulators on percent fruit drop per panicle at different stages of fruit growth in Dashehri mango was studied by Ahmed et … CCC and GA application gave quite beneficial effects on these parameters. Plant Tiss. Prevention of leafing, leaf fall or both. The plants were harvested 85-90 days after sowing in the first week of May, 2006. The foregoing auxins are plant growth regulators widely used in agriculture to control the quality of the crop. Results showed that NAA had positive effect on rooting at the concentration of 200 mg/l compared to other concentrations at 30 days after planting (DAP). Raoofi et al. Color enhancement of fruit. Hormonal Concentrations Used . The treatment of foliar spray of NAA (25 and 50 ppm) and GA3 (150 and 250 ppm) was given at thirty and forty days after transplanting. Among the three soaking durations, 20 minutes (min) of 200 mg/l NAA resulted in higher percentages of rooting, larger numbers of adventitious roots and heavier root dry weight per cutting. Micropropagation of Aloe barbadensis Mill. Effect of IAA on cell division and elongation of cells might have resulted in the increased plant height. Table 1. NAA has been shown to greatly increase cellulose fiber formation in plants. GA 3 significantly increases growth characters, yield and also improved quality of tomato whereas NAA application Concentrations of NAA (Naphthalene acetic acid) and BAP (6-Benzyl Amino Purine) individually as well as in combination had different effects on different stages of tissue culture.
